CFS Carbon Block Water Filter Cartridges for GE GXWH04F, GXWH20F, GXWH20S & GXRM10 – Pack of 4

Elevate your home's water quality

CFS Carbon Block Water Filter Cartridges are designed to fit GE GXWH04F, GXWH20F, GXWH20S, and GXRM10 housings. They feature a larger surface area and depth-filtering action, enabling more thorough filtration while aiming to preserve essential minerals that contribute to a balanced taste and feel.

Unlike simple surface filtration, the depth filtration approach engages multiple layers of the carbon block to reduce a wider range of impurities. The result can be water that feels cleaner through daily use, with a noticeable improvement in flavor and aroma as it moves from faucet to glass.
